Today's augmented reality
projects are still most often just about software. The necessary
display glasses are taken as is. But this has been the same for
the last decade and more, so we cannot really expect any
progress this way. Before this book appeared, most people even
thought augmented reality was for professional applications only,
just because of those bulky goggles.

Essential requirements for display glasses are:

Eye tracker

Mask display

Position cameras

Dynamic image generator

Dynamic fit
and focus adaptation

No straps, no screws,
no belts, no clamps !

In current
products, you will hardly find any of these at all

The technology to realize
all this is available. It cannot only be done, it can be integrated
in a very light and convenient pair of glasses, even containing
its own power supply.
